Hi I have been given

If you are currently overclocking, no point. If not, yes. But if you don't overclock, you should.Another point of view, is it worth it moneywise? No. The performance jump won't be as high as you would hope (2,66-3,2). There is much bigger performance differential when doing 4.2. Going from 3.2 to 4.2 is easier than 2.66 to 4.2, that's for sure. You could expect some 15% performance increase. Doing 30fps, will differ to about 34-35fps. NOT 500 pounds worth imo...

Hi Word Not Allowed Thanks for your advice. As i write i have just finished vewing a tutorial on you tube about overclocking. In the past i have always kept away from it as i was scared i might end up damageing my system. I will keep my fingers crossed that everything goes ok. thanks again. regards shaun

Register and go through xtremesystems forums. They are guys that know inside and outside of overclocking. There are even some fixed settings that are gonna get you up and running at a very high clock in no time. I can only say one thing: temperature is your enemy. Always have to monitor it!http://www.xtremesystems.org/forums/index.php

For FSX performance you are far better off investing in a really good CPU cooler (recommendations anyone?) along with the fastest RAM (no slower than 1600 cas 6) you can get, and then overclock that 920 as recommended by Word Not Allowed. 4ghz or higher, for sure!

Or even go watercooling, which will give you both silent AND great overclocking potential. It's a one time investment, if you are into it.
